Switching cabinet and assembly method of the same

Abstract

A switching cabinet includes a rack. The rack includes two individual frames. Each of the frames includes four braces sequentially coupled together to be rectangle-shaped. The frames are arranged to form front and rear portions of the rack in a depth direction of the rack. An assembly method of the switching cabinet includes steps: 1) providing braces; 2) connecting a part of the braces to form a first frame; 3) connecting the other part of the braces to form a second frame; 4) arranging the first and second frames to form front and rear portions of the switching cabinet in a depth direction of the switching cabinet.

1 . A switching cabinet comprising:
 a rack comprising two individual frames, each of the frames comprising four braces sequentially coupled together to be rectangle-shaped;   wherein the frames are arranged to form front and rear portions of the rack in a depth direction of the rack.   
     
     
         2 . The switching cabinet of  claim 1 , wherein the braces are sequentially welded to form each of the frames. 
     
     
         3 . The switching cabinet of  claim 1 , wherein each of the braces comprises a substantially C-shaped main body, and the main body has an open lateral side facing toward center of area framed by a corresponding frame. 
     
     
         4 . The switching cabinet of  claim 3 , wherein the two of the braces of each of the frames are vertical, and the other two of the braces of each of the frames are horizontal, four vertical braces of the frames each further comprising a first flange extending towards the interior of the rack from an inner edge of the main body and a second flange extending towards the exterior of the rack from an outer edge of the main body. 
     
     
         5 . The switching cabinet of  claim 4 , wherein two horizontal braces located at a top of the rack each further comprises a third flange extending towards the exterior of the rack from an outer edge of the main body. 
     
     
         6 . The switching cabinet of  claim 5 , wherein the third flange has a free side thereof bent inwardly towards the main body to form a baffle plate, the baffle plate being in contact with the third flange, a groove being defined between an inner edge of the baffle plate and the main body. 
     
     
         7 . The switching cabinet of  claim 6 , wherein the first and second flanges of a same brace are parallel to the main body of the same brace and coplanar with each other. 
     
     
         8 . The switching cabinet of  claim 6 , further comprising a top cover covering the top of the rack, wherein the top cover comprises a top board and two inserting sheets extending downwardly from two opposite sides of the top board, the inserting sheets respectively corresponding to the grooves of the two horizontal braces located at the top of the rack to guide liquid on the top board into the grooves. 
     
     
         9 . The switching cabinet of  claim 8 , wherein the second flange forms a groove similar to the groove of the third flange, the liquid in the grooves of the two horizontal braces located at the top of the rack flows into the grooves of the vertical braces and flows out of the switching cabinet. 
     
     
         10 . The switching cabinet of  claim 5 , wherein the main body comprises a main plate and two extending plates extending perpendicularly from two opposite lateral sides of the main plate in a same direction, the first flange connecting with one of the extending plates located at an inner side of a corresponding brace, the second flange connecting with the other one of the extending plates located at an outer side of a corresponding brace, the third flange connecting with one of the extending plates located at an outer side of a corresponding brace. 
     
     
         11 . The switching cabinet of  claim 5 , wherein the first flanges of two vertical braces located at a left side of the rack being coplanar with each other to define a first plane, the first flanges of the other two vertical braces located at a right side of the rack being coplanar with each other to define a second plane, the first plane being spaced from and parallel to the second plane. 
     
     
         12 . An assembly method for a switching cabinet comprising steps of:
 providing a plurality of braces;   connecting a part of the braces to form a first frame;   connecting the other part of the braces to form a second frame; and   arranging the first and second frames to form front and rear portions of the switching cabinet in a depth direction of the switching cabinet.   
     
     
         13 . The assembly method of  claim 12 , wherein each of the first and second frames comprises four braces, two braces being vertical, and the other two braces being horizontal, the braces of each of the first and second frames being sequentially welded. 
     
     
         14 . The assembly method of  claim 13 , further comprising a step of securing a plurality of beams to the vertical braces of the first and second frames. 
     
     
         15 . The assembly method of  claim 13 , wherein each of the beams has an end thereof secured to one of the vertical braces of the first frame and an opposite end thereof secured to one of the vertical braces of the second frame, the one of the vertical braces of the second frame facing the one of the vertical braces of the first frame. 
     
     
         16 . The assembly method of  claim 12 , further comprising a step of mounting a top cover and a pedestal on tops and bottoms of the first and second frames.
